[PATCH] edac: altera: Fix ARM64 warning

[thor.thayer at linux.intel.com]

From: Thor Thayer <thor.thayer at linux.intel.com>

The kbuild test robot reported the following warning on altera_edac.c:

drivers//edac/altera_edac.c: In function 'ocram_free_mem':
drivers//edac/altera_edac.c:1410:42: warning: cast from pointer to integer
      of different size [-Wpointer-to-int-cast]
  gen_pool_free((struct gen_pool *)other, (u32)p, size);
                                           ^^^
After adding support for ARM64 architectures, the unsigned long parameter
is 64bits and causes a build warning with arm64-allyesconfig
Fix by casting to the correct size (unsigned long) instead of u32.

Reported-by: kbuild test robot <lkp at intel.com>
Fixes: c3eea1942a16 ("EDAC, altera: Add Altera L2 cache and OCRAM support")
